We are obviously talking about a different price category of routers. Most routers people use here in Germany for home systems are from their ISP, and they are usually proprietary implementations where you cannot do much more than to configure them by web interface with the enclosed windows software (if you can decide which ports go through you already have an "advanced" router). Unless by experimenting it is close to impossible to decide what the router really does or does not. I wouldn't trust them as far as I can throw a stone.
